OPERATING CONDITIONS (Cont’d)
13.3.4.2 RC oscillator and PLL characteristics (tested for T
Notes:
1. If the RC oscillator clock is selected, to improve clock stability and frequency accuracy, it is recommended to place a
decoupling capacitor, typically 100nF, between the V
2. Data based on characterization results, not tested in production
3. See “INTERNAL RC OSCILLATOR ADJUSTMENT” on page 23.
4. Guaranteed by design.
5. Averaged over a 4ms period. After the LOCKED bit is set, a period of t
6. After the LOCKED bit is set ACC
